S&P 500 closes higher Friday as Amazon surges; Dow posts fourth straight winning month: Live updates

本周五是美股7月最后一个交易日，三大股指集体收高。最亮眼的是亚马逊，股价大涨带动了整个市场情绪。纳斯达克指数涨了1%，标普500涨了0.7%，道琼斯指数也小幅上扬，并且已经连续第四个月保持上涨势头。这次上涨背后其实有两个关键因素。一是投资者对人工智能技术的热情持续高涨，大型科技公司的业绩表现强劲，让大家对AI带动业绩增长充满期待。二是市场普遍预期美联储可能很快降息，水龙头一松，钱就容易往股市里流。对普通人来说，这波行情的影响是间接但实在的。如果你有投养老金、基金或者持有相关指数产品，账户数字大概会跟着好看一些。另外，科技公司股价上涨，意味着它们有更多资金去投入AI研发和应用，未来我们能用到更聪明的AI产品和服务，比如更智能的搜索工具、更懂你的购物推荐。当然，短期波动在股市里很正常，不必因为一天的涨跌就过度兴奋。

Michael Nagle | Bloomberg | Getty ImagesThe major averages were markedly higher Friday, the last trading session in July, as investors looked past rising bond yields and Amazon shares jumped.The Nasdaq Composite rose 1% to end at 25,373.85, while the S&P 500 added 0.7% to close at 7,489.72. The Dow Jones Industrial Average gained 276.97 points, or 0.53%, to 52,485.03.The 30-year Treasury bond yield spiked to its highest levels since 2007 this week. It was last up about 4 basis points on the day at 5.25%. The benchmark 10-year Treasury note yield topped 4.7% on the day, its highest level since January 2025. The moves come as investors lost faith in Federal Reserve Chairman Kevin Warsh's commitment to curb inflation, leading yields to jump. While Warsh indicated he is committed to the inflation fight, he did say this week, "We've got no magic wand." "As [the yield for 10-year Treasury bonds] moves toward five percent, five percent is perhaps a level that will cause angst for sentiment and pressure valuations," Terry Sandven, chief equity strategist at US Bancorp Asset Management, told CNBC. The strategist underscored that this "is a roller coaster market filled with angst and opportunity.""On one hand, there's much to like about the market environment. Inflation is relatively steady, interest rates are range
